LPG removal

[bimmer49]

My V40 BiFuel is nearing it's economical life end.
It needs and engine (burning oil) and the gearbox has a constant grumble (final drive bearings) and the ITV (MOT) is due.
Now I have a Motorhome under renovation (diesel) but has Propane/Butane gas bottles on board.
I was considering removing the tank and filler from the V40 and maybe bolting it to the underside of the MH and doing away with the bottles and then i can refill the tank on the road, saving a bob or two. My gas bottles aren't interchangeable outside of Spain and Portugal, whereas top up available anywhere.
Technically I can do it, my Vehicle Technical card (Fiche Tecnica) say I have gas supply on board but doesn't specify where or for what for.
My question is: In the tank mounted control box, does that reduce the liquid to a gas before it gets to the gizmo with the stepper motor mounted on it (gas distributor?) or is it liquid up to the distributor?
If it's gas from the tank then i'm onto a winner.
Looking at UTube for LPG fitments they all use oblong tank kits with additional gas valve to produce the gas from the liquid. Is the VOLVO one "built in"?
Just an idea......cos the car will probably go for scrap.
PS: Is it worth nicking the gas gauge out of the dash too?

OK so no one knows!!
Anyone got a components list for the VOLVO BiFuel?
WHERE is the vapouriser? Where it turns LPG into 38mBar gas? On the tank or at the distributor?

liquid LPG goes from the tank to the heated vaporiser under the bonnet then gas goes to the distributor then to the the injector valves .

Wrong kind of tank, you will need a vapour take off type tank

[bimmer49]

I would say a gas tank is a gas tank, it's the fittings that are different. I can't use the car vapouriser but a remote gas bottle type vaporiser as used by Gas-it for refillable bottles or the gas conversion fitters (as seen on U tube).
There is an ideal gap for the tank up between the chassis rails at the front of the MH.

gas tank is not a gas tank

Car tank takes liquid, camper tank takes vapour

Step away before the blow someone up and I am not joking.

Keeping an eye out for newspaper headline now

I have been in a stack of LPG vehicles. Not one ever worked reliably, usual was engine management lights, spluttering under full throttle etc etc. Less usual was burnt out valves and engine issues at low miles (less usual but not rare).

Junk it. It’s just not worth the hassle.

Now, if you can buy a professionally equipped one that actually works granted maybe.
